That shoulder injury and the injury he had last year end many careers in Pro Sports.
He will never be 100% again and while he can rehab it, it is his shooting arm, and ya never know. Do you really want to work that hard again at the age of 37 when you are set for life, with a great legacy in place, and plenty of title rings? I think not.
Time to hang up the laces. Shell of his old self on a team that makes him look bad (Lakers suck), money is already in the bank, life is good in LA without basketball and a broadcasting career and other opportunities await him.
